When an attempted revenge plot goes dangerously wrong, Ash inadvertently throws the fire and earth gods into a conflict that can only be settled by deadly, lavish gladiator games, throwing Madoc in Ash's path. She realizes that his powers are the weapon her rebellion needs--but Madoc won't jeopardize his family, regardless of how intrigued he is by the beautiful warrior. But when the gods force Madoc's hand, he and Ash uncover an ancient war that will threaten more than one immortal--it will unravel the world.
